OWC 32GB DDR3L 1600 ECC Registered Kit

This 32GB kit contains four 8GB DDR3L 1600 PC3L-12800 CL11 modules built as 240-pin 1.35V ECC Registered RDIMMs with 1Rx4 organisation. It is designed for Dell PowerEdge R320, R415, R420, R420XR and R515 servers and replaces Dell part numbers A7134886, A7545680, RKR5J and SNPRKR5JC/8G.

For servers needing registered ECC memory.

The modules are ECC Registered RDIMMs, a type used in workstations, servers, NAS systems and routers. They will not work in standard desktop computers that require unbuffered non-ECC memory, and they cannot be mixed with unbuffered modules. Buyers who need unbuffered memory for a consumer motherboard should look elsewhere.

Registered ECC RDIMM with 1Rx4 organisation

The single specification that decides fitment is the Registered ECC RDIMM design with 1Rx4 rank configuration. Only systems that accept 240-pin DDR3L Registered ECC DIMMs at 1.35V can use this kit; any platform requiring unbuffered, non-ECC or a different rank structure will reject these modules.

Questions about this item

Will the 1.35 V DDR3L RDIMMs run alongside existing 1.5 V DDR3 modules in a PowerEdge R420?

No. The manufacturer states these registered ECC modules cannot be mixed with unbuffered memory, and the 1.35 V DDR3L voltage differs from standard 1.5 V DDR3, so all slots should use identical DDR3L RDIMMs.

How can I confirm the kit is running at DDR3L 1600 CL11 after installation?

Enter the server BIOS or use a tool such as CPU-Z; the memory speed should show 1600 MHz (PC3L-12800) with CAS latency 11 and the total capacity should report 32 GB across the four 8 GB modules.

Does the kit include a heat spreader or any extra cables, or must I buy them separately?

The modules have no heat spreader and the kit contains only the four 240-pin RDIMMs; no cables, brackets or cooling accessories are included or required for installation.
